Abstract: A charge/discharge control apparatus includes: a controller which performs a discharge control to discharge a rechargeable battery and a charge control to charge the rechargeable battery using excess power which is power, among generated power, which is not to be consumed by a load; and a setter which sets a threshold value for remaining energy in the rechargeable battery, according to a planned discharged energy amount which is planned as a discharged energy amount to be supplied from the rechargeable battery to the load during a specified time period. The controller performs a discharge prohibition control to prohibit a discharge of the rechargeable battery when the remaining energy in the rechargeable battery is equal to or below the threshold value prior to the specified time period.
